All Saints' Day, a holy day of obligation in some areas (a national holiday in many historically Catholic countries), and its related observance: Day of the Innocents, The first day of Day of the Dead or El Dia de los Muertos celebration. (Mexico, Haiti)

The Massacre of the Innocents is a story recounted in the Nativity narrative of the Gospel of Matthew (2:16–18) in which Herod the Great, king of Judea, orders the execution of all male children who are two years old and under in the vicinity of Bethlehem. Modern scholarship finds no evidence that it happened outside the passages in Matthew, though it is congruous with Herod's character.

The Day of the Dead is a holiday traditionally celebrated on November 1 and 2, though other days, such as October 31 or November 6, may be included depending on the locality. The multi-day holiday involves family and friends gathering to pay respects and remember friends and family members who have died. These celebrations can take a humorous tone, as celebrants remember amusing events and anecdotes about the departed. It is widely observed in Mexico, where it largely developed, and is also observed in other places, especially by people of Mexican heritage. The observance falls during the Christian period of Allhallowtide. Some argue that there are Indigenous Mexican or ancient Aztec influences that account for the custom, though others see it as a local expression of the Allhallowtide season that was brought to the region by the Spanish; the Day of the Dead has become a way to remember those forebears of Mexican culture. The Day of the Dead is largely seen as having a festive characteristic.
